2026-03-30usb: gadget: uvc: fix NULL pointer dereference during unbind raceJimmy Hu
Commit b81ac4395bbe ("usb: gadget: uvc: allow for application to cleanly shutdown") introduced two stages of synchronization waits totaling 1500ms in uvc_function_unbind() to prevent several types of kernel panics. However, this timing-based approach is insufficient during power management (PM) transitions. When the PM subsystem starts freezing user space processes, the wait_event_interruptible_timeout() is aborted early, which allows the unbind thread to proceed and nullify the gadget pointer (cdev->gadget = NULL): [ 814.123447][ T947] configfs-gadget.g1 gadget.0: uvc: uvc_function_unbind() [ 814.178583][ T3173] PM: suspend entry (deep) [ 814.192487][ T3173] Freezing user space processes [ 814.197668][ T947] configfs-gadget.g1 gadget.0: uvc: uvc_function_unbind no clean disconnect, wait for release When the PM subsystem resumes or aborts the suspend and tasks are restarted, the V4L2 release path is executed and attempts to access the already nullified gadget pointer, triggering a kernel panic: [ 814.292597][ C0] PM: pm_system_irq_wakeup: 479 triggered dhdpcie_host_wake [ 814.386727][ T3173] Restarting tasks ...

State Synchronization (flag + mutex) Introduce a 'func_unbound' flag in struct uvc_device. This allows uvc_function_disconnect() to safely skip accessing the nullified cdev->gadget pointer. As suggested by Alan Stern, this flag is protected by a new mutex (uvc->lock) to ensure proper memory ordering and prevent instruction reordering or speculative loads. This mutex is also used to protect 'func_connected' for consistent state management. 2. Explicit Synchronization (completion) Use a completion to synchronize uvc_function_unbind() with the uvc_vdev_release() callback. This prevents Use-After-Free (UAF) by ensuring struct uvc_device is freed after all video device resources are released.

2026-03-30drm/xe: Avoid memory allocations in xe_device_declare_wedged()Matthew Brost
xe_device_declare_wedged() runs in the DMA-fence signaling path, where GFP_KERNEL memory allocations are not allowed. However, registering xe_device_wedged_fini via drmm_add_action_or_reset() triggers a GFP_KERNEL allocation. Fix this by deferring the registration of xe_device_wedged_fini until late in the driver load sequence. Additionally, drop the wedged PM reference only if the device is actually wedged in xe_device_wedged_fini.

However, this case is impossible to hit because we're switching on an enum and all the valid enum values have their own cases.

Commit 710abda58055 ("gpio: shared: call gpio_chip::of_xlate() if set") introduced a critical section around the adjustmenet of entry->offset. However this may cause a deadlock if we create the auxiliary shared proxy devices with this lock taken. We only need to protect entry->offset while it's read/written so shorten the critical section and release the lock before creating the proxy device as the field in question is no longer accessed at this point.

2026-03-30drm/i915/dsi: Don't do DSC horizontal timing adjustments in command modeVille Syrjälä
Stop adjusting the horizontal timing values based on the compression ratio in command mode. Bspec seems to be telling us to do this only in video mode, and this is also how the Windows driver does things. This should also fix a div-by-zero on some machines because the adjusted htotal ends up being so small that we end up with line_time_us==0 when trying to determine the vtotal value in command mode. Note that this doesn't actually make the display on the Huawei Matebook E work, but at least the kernel no longer explodes when the driver loads.

2026-03-27net: enetc: do not allow VF to configure the RSS keyWei Fang
VFs do not have privilege to configure the RSS key because the registers are owned by the PF. Currently, if VF attempts to configure the RSS key, enetc_set_rxfh() simply skips the configuration and does not generate a warning, which may mislead users into thinking the feature is supported. To improve this situation, add a check to reject RSS key configuration on VFs.

2026-03-27net: sfp: Fix Ubiquiti U-Fiber Instant SFP module on mvnetaMarek Behún
In commit 8110633db49d7de2 ("net: sfp-bus: allow SFP quirks to override Autoneg and pause bits") we moved the setting of Autoneg and pause bits before the call to SFP quirk when parsing SFP module support. Since the quirk for Ubiquiti U-Fiber Instant SFP module zeroes the support bits and sets 1000baseX_Full only, the above mentioned commit changed the overall computed support from 1000baseX_Full, Autoneg, Pause, Asym_Pause to just 1000baseX_Full. This broke the SFP module for mvneta, which requires Autoneg for 1000baseX since commit c762b7fac1b249a9 ("net: mvneta: deny disabling autoneg for 802.3z modes"). Fix this by setting back the Autoneg, Pause and Asym_Pause bits in the quirk.

2026-03-27eth: fbnic: Account for page fragments when updating BDQ tailDimitri Daskalakis
FBNIC supports fixed size buffers of 4K. When PAGE_SIZE > 4K, we fragment the page across multiple descriptors (FBNIC_BD_FRAG_COUNT). When refilling the BDQ, the correct number of entries are populated, but tail was only incremented by one. So on a system with 64K pages, HW would get one descriptor refilled for every 16 we populate. Additionally, we program the ring size in the HW when enabling the BDQ. This was not accounting for page fragments, so on systems with 64K pages, the HW used 1/16th of the ring.

2026-03-27accel/qaic: Handle DBC deactivation if the owner went awayYoussef Samir
When a DBC is released, the device sends a QAIC_TRANS_DEACTIVATE_FROM_DEV transaction to the host over the QAIC_CONTROL MHI channel. QAIC handles this by calling decode_deactivate() to release the resources allocated for that DBC. Since that handling is done in the qaic_manage_ioctl() context, if the user goes away before receiving and handling the deactivation, the host will be out-of-sync with the DBCs available for use, and the DBC resources will not be freed unless the device is removed. If another user loads and requests to activate a network, then the device assigns the same DBC to that network, QAIC will "indefinitely" wait for dbc->in_use = false, leading the user process to hang. As a solution to this, handle QAIC_TRANS_DEACTIVATE_FROM_DEV transactions that are received after the user has gone away.

2026-03-27i2c: designware: amdisp: Fix resume-probe race condition issuePratap Nirujogi
Identified resume-probe race condition in kernel v7.0 with the commit 38fa29b01a6a ("i2c: designware: Combine the init functions"),but this issue existed from the beginning though not detected. The amdisp i2c device requires ISP to be in power-on state for probe to succeed. To meet this requirement, this device is added to genpd to control ISP power using runtime PM. The pm_runtime_get_sync() called before i2c_dw_probe() triggers PM resume, which powers on ISP and also invokes the amdisp i2c runtime resume before the probe completes resulting in this race condition and a NULL dereferencing issue in v7.0 Fix this race condition by using the genpd APIs directly during probe: - Call dev_pm_genpd_resume() to Power ON ISP before probe - Call dev_pm_genpd_suspend() to Power OFF ISP after probe - Set the device to suspended state with pm_runtime_set_suspended() - Enable runtime PM only after the device is fully initialized Fixes: d6263c468a761 ("i2c: amd-isp: Add ISP i2c-designware driver") Co-developed-by: Bin Du <bin.du@amd.com> Signed-off-by: Bin Du <bin.du@amd.com> Signed-off-by: Pratap Nirujogi <pratap.nirujogi@amd.com> Cc: <stable@vger.kernel.org> # v6.16+ Acked-by: Mika Westerberg <mika.westerberg@linux.intel.com> Reviewed-by: Mario Limonciello (AMD) <superm1@kernel.org> Reviewed-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com> Signed-off-by: Andi Shyti <andi.shyti@kernel.org> Link: https://lore.kernel.org/r/20260320201302.3490570-1-pratap.nirujogi@amd.com
